A suicide bomber targeted a crowd of police in the Afghan city of Kunduz on Saturday, killing 10 police officers, the provincial police chief told CNN. Twelve civilians were injured in the bombing.

The police officers were gathered in the center of Kunduz, the capital of a province of the same name, when the bomber detonated his explosives, said Abdul Khalil Andrabi, chief of police for Kunduz province.

Two senior officers -- the head of the counterterrorism unit and the head of the traffic police -- were among those killed, Andrabi said.

Eight other officers lost their lives, he said.

The Taliban claimed responsibility for the bombing, Taliban spokesman Zabiullah Mujahid said in a written statement.
